I’m looking to buy a 1986 2+2 5 speed. It looks almost perfect except for a cracked crank. Seller said the engine still has good oil pressure but you can hear the cracked crank when you rev it up. They said it’s not a rod knock though. What should I know about this? How much would a new crank/repair be? I’m relatively new so I’d need to get this professionally fixed too. Thanks!<br />

Cracked ''how'' exactly?<br />
<br />
Kinda sounds like bullshit.<br />
<br />
These engines commonly make tapping noise on the top end from lifters and fuel injectors clicking, that's kinda normal.<br />
<br />
The woodruff keyway on these cranks can chip, but nothing gets a "crack" without an almost immediate catastrophic failure.<br />
<br />
A replacement crank would be relatively cheap, the parts and labor to install it would not be cheap. It involves pulling the motor entirely apart.<br />
<br />
I'd hightly encourage you to look elsewhere for another Z.</div>z31p_OOlds
